34
Q

What did Steven Heckers say about the hippocampus in the American Journal of Psychiatry?

A

That there was “compelling evidence” that a portion of the hippocampus was activated and “is impaired in early psychosis,” with this activity being related to “hyperactivity of the region in question, which is the anterior hippocampus.”

35
Q

More from Dr. Steven Heckers

A
  • The hippocampus allows formation of and recall of memory, as well as orientation to and navigation in space.
  • “Normal hippocampal function depends upon a balance of excitation and inhibition of the nerve cells that comprise the structure.”
  • The author “an imbalance of these forces has a causal role in the development of schizophrenia – typically beginning with a “first episode” of psychosis, in the late teen or early adult years.”
